David and I talked to MessageLabs' chief architect Paul Fletcher at INBOX/IT before I swanned off on hols. (Yes, for those HP Pinewood or OpenMail old-timers, that Paul Fletcher.) He was talking about a disturbing new trend for high-placed individuals to be carefully targeted with malformed MS Office documents, which contained a Trojan horse. Fiendishly clever.
Seems like the NISCC has figured this out, too.
